Revelation 1:4-8

4John to the seven churches that are in Asia: Grace to you and peace from him who is and who was and who is to come, and from the seven spirits who are before his throne,
5and from Jesus Christ, the faithful witness, the firstborn of the dead, and the ruler of the kings of the earth. To him who loves us and freed us from our sins by his blood,
6and made us to be a kingdom, priests serving his God and Father, to him be glory and dominion forever and ever. Amen.
7Look! He is coming with the clouds; every eye will see him, even those who pierced him; and on his account all the tribes of the earth will wail. So it is to be. Amen.
8I am the Alpha and the Omega, says the Lord God, who is and who was and who is to come, the Almighty.
